we had a fantastic stay at Effies hostel, our room was clean and good value for money. we liked the stylish finishing touches throughout the property.
The location is great, it's close to the Wat Phra Chetuphon temple and not too far from the party times on khaosan road (we walked back from khaosan road one evening and it took us about 20 minutes).
We would have given a five star review but unfortunately there was a leak in our room due to heavy rain fall which could do with some repair. That aside we really enjoyed our stay and would stay again!
